I can't see it making much more than 600fwhp, not enough head/small cam for them cubes to make mid to upper 600's in my opnion.

My mates 440 Dart with 12.7:1, Eddy std port MCH 325cfm heads, DC.590 solid purple cam, 1050 Dom., Victor int...just managed to hit the 600fwhp mark according to best mph/weight. and that cam was done at 6600rpm, car would slow if he shifted it over 6400 through the gears.

For sure the low-ish lift of the cam(for this combo) doesn't play into the -1's attributes, especially earlier ones.

The last set I did(with cnc'd chambers) flowed 297@.600 ootb, and about 340@.600 after proper prep.

I feel like the 10.5cr is a bit low for the basic combo as well.

If the heads were similar to the last ones I did, and I had it on our dyno here, I'd be looking to be in the 650+ range........ It is a 511 after all.I'd have used 1.6 rockers for a cam like that in this type of build.

Whose dyno?? On a few dynos quoted on here, I'm sure it would show over 800...

LOL

We have (42) SAE calibrated engine dyno's. Our Dyno's have to be calibrated because of all of the OEM prototype developement & production work we do so our Dyno's are usually about 15% less than the average Joe. Believe me, you walk into most single dyno engine shops & say you want to make approx 800 HP they can make it make the number pretty easily when it is probably making more like 680ish HP.

Cant see that combo being anything much over 600hp for sure of if it even got there. But as been pointed out dynos are dynos and not all of them spit out the most accurate of results for sure. Id say at Mountain View that combo would struggle to see 575, that's where I have my most recent dyno experience.

Sorry, typo it was late. 265 and 270 @ .050I intend to spin it to 6500-7000. Thanks.

Be lucky to break 600 hp, probably more like 575,???

That cam @ 265 intake is smaller them the MP 590 @ 271 @ .05 you were using. But with the new engine you will be making a lot of torque. To make HP you need to spin them a bit. Your not going to be able to spin that new engine very high in its hp band with that small of cam. It will be done by 6000 rpm. Typical 500" motors with your comp can hit around 600 HP with the mp 590, your using a even Smaller cam.

I am guessing your goal might be 10.01 et? Just a thought, has anyone had good luck with 1.7 ratio rockers and beehive springs? That would get you .630 + net lift on the intakes, and raise the net lift everywhere, which i would think should be well worth the trouble, and cheap power to boot.

We always do this at work with alot of the race engines we build. Sometimes it's $1.00 per person per guess, sometimes $5.00 per guess. Winner gets the pot. We did this on my Hemi when we dyno'd it. So many were so close but it did make more than everyone was expecting.

Here is a engine we just did. Its a 496 with the same cam and compression on pump gas. It has Max Wedge Port SR Heads as received from Indy with NO porting, just our valve job. It has a 440-2 Intake and a 950 Quick Fuel.

With the 440-1 Heads and the 400-3 Intake with a 4500 Carb it will make more than this with out a doubt.
